Environment Environment shows products that are verified to work for the solution described in this article. This solution might also apply to other similar products or applications. Software LabVIEW Model Interface Toolkit MATLAB Models can be executed and communicated with using the Model Interface VIs provided by the LabVIEW Model Interface Toolkit. This tutorial will show you how to compile a Simulink Model in MATLAB for a Windows target and use it with the LabVIEW Model Interface Toolkit. Software SetupMATLAB R2019aMicrosoft Visual Studio 2017 (select Desktop development with C++) - CompilerLabVIEW 2021 SP1 (64-bit)LabVIEW Model Interface Toolkit 2021 - VeriStand 2021 Model Framework will be includedSteps to Compile Simulink ModelFirst make sure that you have installed compatible MATLAB, Compiler and LabVIEW versions by referring to this link: VeriStand LabVIEW Modeling and Legacy Simulink Modeling Version Compatibility.Open MATLAB, and make sure that it shows the version of VeriStand Model Framework.Run mex -setup in the MATLAB software and select a compatible version of Microsoft Visual C++. In this case, since we using LabVIEW 2021 SP1 we need Microsoft Visual Studio 2017 (select Desktop development with C++) as the compiler.Create a simple model in Simulink, for example in the picture below:Set the correct compiler setting for Windows target, please refer to Build the Compiled Model in Simulink subtopic from this link: Compiling a Model from MathWorks Simulink® Software (Model Interface Toolkit) .Press the Build Model to compile the Simulink model and make sure that the build process is completed successfully. It will generate the DLL file for the Windows target. Run the LabVIEW software and open the MIT Get Model Information VI from the LabVIEW example finder.Find the file path for your compiler model, in this example is add.dll. Then, run the example and it will verify the model and report the properties of Inports, Outports, Parameters and Signals. Was this information helpful?

I'm aware this is a bit of a long shot, but it wouldn't be the first time matlab's capabilities have surprised me.For a project, I have to make rovibrational fits to a nitrogen optical emission spectrum. The problem is that I have several thousand spectra and more to come. It would take me weeks to process them manually and so I want to automate this using Matlab. I got a program that can do these fits, but it is a labview .exe file and I have not received the source code. I was wondering if it is still possible to connect the two.What I would like to do:- Have Matlab give LabView a file- Tell LabView to make a fit (the program has a designated button for this, if that helps)- Save or extract the fitted parameters (it has a button for this as well)- Save or extract the fitted curve (also a button)e=actxserver('LabVIEW.Application');vipath='C:\Users\...\fit_spectra_N2_SPS_main.exe';vi=invoke(e,'GetVIReference',vipath);Obviously this wants a vi, so I tried finding what sort of method the ‘.exe’ file would be, but couldn’t find that. If I try it like this, I get the error:Error using COM.LabVIEW_Application/GetVIReferenceInvoke Error, Dispatch Exception:Description: LabVIEW: (Hex 0x423) Unexpected file type.After a lot of googling and coming up empty-handed, the last thing I tried was ask a friend who - though he's not very familiar with matlab - has a lot of programming experience. He expected it to be impossible, but recommended I ask here regardless.So is it possible to control a labview executable (which I do not have the source code for) with matlab?If it does happen to be possible, can you point me in the right direction to get started? Because I honestly have no idea how to go about it anymore.
